The <code>em</code> unit is relative to the <code>font-size</code> of its <b>parent element</b>. <code>rem</code> stands for \"root em\", it's only relative to the <b>root element</b> (<code>html</code>). It makes <code>rem</code> unit more predictable and easier to manage in large websites."

This makes your website more accessible to users who increased the <code>font-size</code>. <code>em</code> unit allows for more flexible and responsive design, as they adjust based on the parent element's font-size."

For example: <code>width</code>, <code>height</code>, <code>padding</code>, <code>margin</code>, and <code>line-height</code>. Using <code>em</code> unit for these kind of style properties can help maintain proportional layout for different screens sizes."

          "@type": "Answer",
          "text": "If you nest elements which are using <code>em</code> unit, the child element's size will be relative to the parent element's size. This can lead to cases where the size of the child element becomes larger or smaller than expected. To avoid this, you can use <code>rem</code> unit, which is always relative to the root element's (<code>html</code>) size."

          "@type": "Answer",
          "text": "While <code>em</code> unit offers many advantages, it can be difficult to manage than absolute units like <code>px</code>. Because <code>em</code> unit is relative, its actual size can change based on the parent element's size. It can make it <b>harder to predict the size of elements</b>, especially in complex layouts."

Because <code>em</code> units are relative which means, they adjust based on the user's browser settings. It means your media queries will adapt to the user's settings."

          "text": "To calculate the size of nested elements with <code>em</code> unit, you <b>multiply the parent element's size by the child element's size</b>. For example, if the parent element's size is <code>1.5em</code> and the child element's size is <code>2em</code>, the actual size of the child element would be <code>1.5 * 2 = 3em</code>. It's because the child element's size is relative to the parent element's size."
